unfortunately as a source I don't have a pc but an ibasso dx220 reader and the parametric eq I could use that of the UAPP reader but I don't understand it well because the most important wording "peak" is missing
Not, It cannot. Cables won't affect resolution. If you wanna improve the MGs, parametric EQ is the best you can do.
It's called analog bell on the UAPP equalizer.
Digital parametric EQ, aka PEQ for short, yes everyone can use it if they want, there are many options both on desktop and mobile.
Not likely. It may give some slight tone differences. How much is hard to say because the amount is subtle enough that it could be placebo and "you want to hear it" since you spent so much money. Yes, silve is better conductor than copper. Then again, you're not running some significantly long cable. A good OFC copper will serve you well. As stated by a few in pervious posts in this thread, spending money a new cable is able to construction and qaulity of build. You can get a cable that is more durable or significantly less microphonic.
Thanks from what I understand in the case you describe there are 2 options for peQ : oratory 1990 and autoeq?Digital parametric EQ, aka PEQ for short, yes everyone can use it if they want, there are many options both on desktop and mobile.
AutoEq has PEQ presets. In other words, it has data, results, to set PEQ to tune a headphone to the harman target. The database is huge, for both full size and in ear headphones. It's also based on all major measurements sites' data. So one can choose tuning based on different measurement results for the same headphone.
The best thing is that the presets consist of many frequency "bands" for every headphone, so you can choose to just tune the treble and leave the rest of the spectrum unaffected.
Example for Focal Clear Mg AutoEq harman tuning PEQ preset, based on oratory1990 - measurement (oratory1990 has it's own presets, in the measurement sheet, as well):
Preamp: -6.8 dB
Filter 1: ON LSC Fc 105 Hz Gain 5.9 dB Q 0.70
Filter 2: ON PK Fc 8639 Hz Gain 6.2 dB Q 1.17
Filter 3: ON PK Fc 1197 Hz Gain -4.0 dB Q 1.73
Filter 4: ON PK Fc 94 Hz Gain -4.2 dB Q 0.31
Filter 5: ON PK Fc 4532 Hz Gain 5.5 dB Q 3.15
Filter 6: ON HSC Fc 10000 Hz Gain -3.4 dB Q 0.70
Filter 7: ON PK Fc 2223 Hz Gain 1.7 dB Q 4.29
Filter 8: ON PK Fc 3197 Hz Gain -1.7 dB Q 3.02
Filter 9: ON PK Fc 3987 Hz Gain 1.4 dB Q 6.00
Filter 10: ON PK Fc 7340 Hz Gain 1.5 dB Q 5.95
Those are just the presets, aka how to adjust the EQ. You can find a complete list of software and preset options under my profile about page. ASR tutorials and resources links and other miscelaneous resources links.
Too generic. We need to know the whole chain in detail.
You should use analog bell instead of digital one. Graphic EQ is far inferior than parametric EQ. You can't judge based on a profile. You can use those profiles to have a reference and adjust it to your liking because not all people like the EQ adjusted to full Harman.
